OK, I'm thoroughly confused now...
I'm taking "combining PS4/XB1" as meaning just their exclusives, as in their 1st/2nd party games. Things like Titanfall, Infamous, Drive Club, The Order, etc against Ninty exclusives. In other words, not including games like Metal Gear or Destiny. In that scenario I think WiiU will win.
However, if you mean combining everything that's exclusive to PS4/XB1 as in everything not coming to WiiU (which would pretty much be their entire libraries except for Watchdogs and COD), then yeah, PS/1 will win.
